HOSE-COUPLING'.

Patented Sept. 2,1913.

Application filed August 23, 1912. Serial No. 716,635.

To all whom it my concern Be it known that I, ROLAND C. HILTON, a citizen of the United States, residing at Boston, county of Suffolk, State of Massaehusetts, have invented an Improvement in Hose-Couplings, of which the following description, in connection with the accompany ing drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to hose couplings of that known type wherein one of the coupling muembers is provided with receding blocks having screw-threaded faces that are adapted to engage the screw-threads of the other coupling member so that the two coupling members can be coupled by merely a longitudinal movement of one relative to the other.

The object of my invention is to provide a novel coupling of this type having' the features which will be more fully hereinafter described and then pointed out in the appended claims.

Referring to the drawings wherein I have illustrated the preferred embodiment of my invention, Figure 1 is a sectional view of my improved coupling on the line m-m, Fig. 2; Fig. 2 is a section on the line 1/-y/, Fig. 1; Fig. 3 is a fragmentary sectional view showing' a different form of lock from that shown in Fig. 2; Fig. 4 is a fragmentary section on the line a-a, Fig. 1; Fig. 5 is a perspective view of the ring 7.

3 designates a coupling member having the exterior screw-threaded portion 4 adapted to screw into a female coupling member and also having provision for being coupled to a male coupling member 5. The coupling member 3 is provided with a plurality of receding blocks 6, each of which has screwthreads on its interior face adapted to engage the screw -threaded member 5, said blocks receding when the members are coupled to permit the quick coupling movement. These receding' blocks 6 are mounted in a ring 7 which is situated within the coupling 3, said ring' being provided with radial apertures 8 in which the blocks slide back and forth. Each of the blocks G is provided on its back with a notch or groove 9 in which is received a spring 10 that tends to force the blocks inwardly. Said spring can preferably be a coiled spring which encircles all of the blocks, although any other yielding means for holding' the blocks 6 forward may be employed. The blocks 6 are longer than the thickness of the ring 7 so that the outerl ends of the blocks project through the ring and occupy an annular recess 12 formed in the member 3. The projecting portion of each block 6 is provided with a beveled face 11 and the recess 12 is provided at one side with a specially-shaped face which cooperates with the beveled faces 11 in holding the receding blocks G to their work, as will be presently described. The ring 7 is capable of moving longitudinally within the coupling member 3, and when said ring' is moved backwardly against the wall 14, then the blocks 6 are free to be moved outwardly in a radial direction, while when the ring 7 is in its forward position, as shown in Fig. 1, and is held in such po sition the blocks G are locked in their operative position. The inward radial movement of the blocks G is limited by a stop ring 15 which is situated within the ring' 7 and is situated to be engaged by the blocks G.

In coupling the member 3 to the male coupling member 5 the latter is inserted into the member 3 and when the screw-threads thereon engage the screw-threaded blocks 6, the ring' 7 with the blocks therein will be carried backwardly against the wall 14. When the ring 7 has reached this position, then during' further entering' movement of the male member 5 the blocks G will be forced baekwardly against the act-ion of the spring 10 and will click over the screw threads of said member 5.

lVhen the two members are coupled together and the screw-threaded faces of the blocks 6 engage and fit the screw-threads on the member 5, the blocks 6 occupy their inward position owing to the action of the spring 10 and the coupling is then tightened by simply giving the member 3 a partial turn. I have provided means whereby when the member 3 is thus given a partial turn the ring 7 will, be forced toward the front, thus bringing the blocks into locking engagement with said member. The member 3 is shown as having one or more V-shaped projections 31 thereon and the ring 7 has complemental shaped recesses 3Q. The pro jections 31 and recesses 89. normally stand in line with each other and when the ring 7 is pushed backwardly during' the time that the member 5 enters the member 3, the projections enter the recesses. lVhen the coupling has been forced onto the male memof the recesses 32 and the camming action V which results forces the ring 7 forwardly in the member 3.

The front face of the recess 12 is provided with two inclined portions 34, 35 separated by the shoulder 36, and said shoulder is so positioned that when the ring 7 is forced forwardly into its locking position the ends of the blocks 6 will just engage the shoulder 36, as seen in Fig. 1. This shoulder 36 acts asy a means for locking the block 6. from backward rotation.

The ring 7 is an important feature of the invention for it causes all of the blocks 6 to move in unison in an axial direction as the male member 5 isentered into the coupling. This insures that all of they blocks. will be operative in effecting the coupling.

It will be noted that the ring 7 yhas a diameter equal to the interior diameter of the chamber in the end of the coupling member 3. In assembling the parts the blocks 6 are rst mounted in the ring but located therein sov that the outer ends of the blocks do not project beyond the periphery of the ring and then said ring with the blocks therein is slipped into the coupling member 3. The blocks 6 are then forced outwardly into the position shown in Fig. 1 and the stop ring 15 is put in place. The outer projecting ends of the blocks 6 serve to prevent the ring 7 from being withdrawn from the coupling, and the ring 7 holds all of the blocks in alinement and insures that they will all act. simultaneously during the coupling operation.

My invention also includes a lock to hold positively theV ring 7 in its forward position when the two coupling members are coupled together, thus locking positively the blocks 6 in their operative position.y In Fig. 2 this lock is shown as a locking lever 2,0. pivoted at 21 and provided with a lockinglip 22 that is adapted to enter behind the ring 7 between the latter and the wall 14. This locking lever 20 is shown as having an extension 23 which extends through the periphery of the member k3 and provides a thumb-piece by .which it can be thrown out of operative position. normally holding the locking lever in its` operative position.

In Fig. 3 I have shown another embodiment of the invention wherein the locking member is in the form of a push-button 45 which plays in a radial aperture in the member 3. The push-button is normally held in its operative position by means of a Vspring 46, and when in such position the portion 37 `thereof is situated between the ring 7 and the wall 14, thus locking the ring 24 is a spring for f -with a body having in one end thereof a chamber provided with a recess in its exterior wall, of a ring within said chamber, f said ring being of a size to permit it to be inserted axially into saidchamber and being iprovided with radial apertures,and blocks l mounted in said apertures for radial movein its forward position. This push-button .f is provided with a notch 28 which'is brought into alinement with the ring 7 when. the

push-button is depressed, and when the parts are in this position the ring 7 is permitted to move rearwardly against the wall 14. The ring 7 is shown as provided with a notchA or recess 41 to receive the portion 37 of the push button when the latter is depressed and the ring is forced rearwardly.

In coupling the two members together the operator depresses the push button so as to release the lock, thus permitting the ring 7 to have its rearward movement as above described. Vhen the members are coupled together, then the push button is released, aiid the lock is moved into an operative po-A sition thereby locking the ring 7 in itsv forward position. Y A A Having fully described my invention what I claim as new and desire to secure by Letters Patent is 1. In a coupling member, the combination with a. body having in one end thereof a chamber provided with a recess in its exterior wall, of a ring within said chamber,

said ring being of a size to permit Vit to be inserted axially into said chamber and being provided with radial apertures, and blocks mounted in said apertures for radial movement, said blocks having their inner faces provided with screw-threads and having a greater length in a radial direction than the thickness of the ring whereby the outer ends of the blocks project through the 4 ring and prevent the latter from being` withdrawn.
